repeating my comment posted
repeating my comment posted today at YouTube:
Re: NVMe RAID: I honestly don’t know what it’s going to take for motherboard and CPU manufacturers to realize that NVMe is capable of replacing SATA storage. And, it’s now well known that DMI 3.0 forces a low ceiling on NVMe RAID performance. If “4×4” bifurcation support is considered a “premium” feature, for marketing purposes, then at a minimum let’s see full support for 4×4 (aka x4/x4/x4/x4) without silly and unnecessary restrictions, like requiring only certain brands of NVMe SSDs. And, forgive me for being blunt, but when Allyn “dangled his dongle” he made a much better statement than reams of text could possibly have done. Hey, folks, NVMe is here to stay. Let’s get serious and eliminate all of the hurdles that stand in the way of general-purpose 4×4 support, from the factory. To repeat, there is an obvious engineering elegance that obtains with 4 x NVMe SSDs @ x4 PCIe 3.0 lanes = x16. This elegance will quickly DOUBLE when PCIe 4.0 becomes widespread. As any casual look at recent history will confirm, the PC industry has enjoyed multiple video cards with x16 edge connectors for at least a decade. Solid-state storage deserves the same raw bandwidth, which is painfully NOT available from Intel’s DMI 3.0 link. [End of rant]
For the mailbag: I am curious

At YouTube, one comment
At YouTube, one comment complained that I wanted to “wipe out SATA”. Here’s my reply to that comment:
Toms Tech, yes, my comment should not be interpreted to mean that I wish to “wipe out SATA”. Forgive me if what I wrote implied that in any way. You are correct: as things stand today, there are too many restrictions preventing a fresh install of Windows (or other OS) to a “4×4” add-in card hosting 4 x M.2 NVMe SSDs. At the Storage Developer Conference back in 2012, we proposed that storage subsystems should “sync” with chipsets. What I would like to see happen with future SATA standards is a similar policy, perhaps one that supports variable transmission speeds e.g. 6G, 8G, 12G and 16G. SATA-IV should also support the 128b/130b “jumbo frame” that is already a feature of PCIe 3.0. For example, a single 8G channel + jumbo frame increases max bandwidth to 985 MB/second, and most quality SATA SSDs are already hitting the current ceiling of 600 MB/second (allowing for controller overhead). As long as SATA remains a single digital channel, it certainly can co-exist with M.2 NVMe devices that use x2 or x4 (or more) PCIe lanes. Indeed, we can now foresee a variety of NVMe add-in cards with x8 and x16 edge connectors. Just yesterday, I emailed to the guys at PCPER.com some links to the ADATA SR2000CP, which uses a PCie 3.0 x8 interface and supports ~6Gb/second READs. Hope this helps.
Looks interesting with GF
Looks interesting with GF going with LASER induced Copper Grain Growth and Intel’s using Cobolt for some metal layers.
The Fuse/Wikichip article states:
“GlobalFoundries Cu interconnect extension
GlobalFoundries has been working on copper interconnect scalability extension for a while now. This year they are back to talk about their results on laser-induced grain growth within Cu interconnects. They claim a 30% line resistance reduction in Copper interconnects, delivering 15% improvement in RC and IDsat improvement of 2-5%.” (1)
